Can you work out pressure from volume?
No. For a gas, temperature also comes into the equation.
What is a pressure differential?
its pressure between suction and discharge flow...
Is the amount of pressure in a gas measured in pascals?
Yes.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
Why should other parameters be kept constant when using specific gas law?
I guess you're talking about the PV=nRT equation; well the volume of a gas depends on the temperature so of course the temperature must be kept constant or your pressure will be affected. The moles of the gas will also affect the pressure. Usually this equation is used to calculate the number of moles it will take to occupy a certain volume or vice versa at standard temperature and pressure: 1 atm and 0 degrees Celcius.
What you mean by cold differential set pressure of a safety valve?
cold differential test pressure -The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
What are the factors that affect the products of a chemical equation?
temperature, pressure, concentration
Can you work out pressure from volume?
No. For a gas, temperature also comes into the equation.
What is the equation for boyles law?
Pressure x Volume = Constant (at a constant temperature).
What is the equation for nitrogen gas plus hydrogen gas under pressure and at high temperature?
the balanced equation is N2 + 3H2 = 2NH3
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
How are temperature air pressure related?
If the temperature of a system is increased, but the volume remains constant, the pressure will increase. If Pressure is increased, then temperature will increase. They are directly proportional, as shown by the combined gas law equation, (V1P1)/T1=V2P2/T2
What law relates pressure and temperature at a constant volume as temperature increases pressure increases?
You can use the Ideal Gas Equation: pV=nRT or p1V1/T1 = p2V2/T2
Differential pressure switch of thermopac?
Yes, the differential pressure switches off the thermopac. Differential pressure switch shut off unit in case of abnormal thermic fluid flow condition.
How does differential heating affect pressure?
Differential heating creates high-and-low-pressure areas, creating wind.
How do you make a calibration for differential pressure?
Differential pressure is the difference between two pressures. So, P2-P1.
Force per unit area defines which of the following a) pressure b) gravity c) force d) temperature?
pressure
